Then Jesus told his disciples, “If anyone would come after me, let him deny himself and take up his cross and follow me.” Matthew 16:24 (ESV)
Today we continue our series on symbols of our Christian Faith, focusing on the Tau-Rho.
The Tau-Rho may be a Christian symbol that is familiar to you, or, perhaps not. You may have seen it represented, but may not know what the background-origin is of the symbol.
The Tau-Rho is an abbreviation of the Greek word for “cross” (stauros), and was used in very early New Testament manuscripts. The abbreviation itself is the superposition of two Greek letters: Tau (T) and Rho (P). The superpositioning of the two Greek letters Tau and Rho (placing one letter on top of the other) creates a coinciding symbol also known as the staurogram or monogrammatic cross. The T represents the cross. The P represents Christ. Put together, the symbol represents Christ on the cross ⳨.
There is a principle in mathematics known as the superposition principle. This principle states that the net response caused by two or more stimuli (a thing that promotes activity or energy in someone or something) is equal to the sum of the responses that would have been caused by each stimulus individually. A function that satisfies the superposition principle is called a linear function. Linear meaning a straight line of progress from one step to another.
Putting the Tau-Rho together with the superposition principle applies directly to being a follower of Christ. The Cross and Christ on the Cross promote a response to believe and follow Christ’s example of giving ourselves to God’s plan for our lives. Submitting to His will. Allowing Him to superimpose himself on our hearts and minds and bodies and live for Him instead of ourselves.
Christ’s life was a linear function. He followed a straight line of progress from one step to another, submitting to God the Father each step along the way of His life to fulfill the sum of His purpose. To give His life for ours so that we might have life eternal if we believe in Him.
When we follow Christ’s example, progressing through life’s challenges in submission to His will, we progress from one step to another to fulfill the sum of our purpose, which is to glorify God. We are made in His image. The Tau Rho symbol is an image of Christ and His sacrifice for us. Let that symbol be a reminder and a rallying cry for each of us as we journey together through the life that God has so richly blessed us with.
Daily Battle Order:
As Easter, Resurrection Day approaches, think about these symbols of the Christian faith from the perspective of those who have gone before us. Those Christian “resistance fighters”, many of whom gave their lives for the cause of Christ, and used these symbols as ways to identify with one another as encouragement and as followers of Christ.
Join us tomorrow as we learn about another sign/symbol that Christians have used, the Iota-Eta Monogram .
Kingdom Men: The Joshua Commission invites you to join us for spiritual warfare battlefield training on the Chickamauga Battlefields; Friday- Sunday, April 9-11 2021.
